... 7.1 Introduction to media types . ... 7.3 Recognized media types . 7.3.1 Media groups One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'cue-before' property for aural user agents). ... For example, the 'font-size' property is useful both for screen and print media. ...

Each catalogue should contain one or more tables. 2) The names of the catalogues should be unique, as well as the the names of tables of the SAME catalogue. ... 4) All the metadata about the CAS system, its tables, catalogues should reside in separate schema (currently "cas_metadata"). 1) The main system table of CAS is the table "catalog_list". ... short info (column "info") . ... 2) The second system table of CAS is the table "table_list". ...

... Physical Properties of Crystals . ... The course is an introduction into crystal physics and consists of two introductory parts devoted to the basics of crystallography and tensor analysis and six main chapters in which the physical phenomena in anisotropic medium are described by the example of the elastic, electrical and magnetic crystal properties. The effect of symmetry is also discussed. ... Effect of symmetry on crystal properties. ... Effect of symmetry on crystal optical properties. ...

... More than 300 surface reconstructions are already known for pure Si surface and Si surface with adsorbate. Study of their properties by the methods of surface physics reveal numerous interesting phenomena including various phase transitions accompanied by changes of Fermi-surface topology, development of the charge-density wave, etc . ... The charge-density wave (CDW) develops in materials with a chain-like crystal structure at temperatures below the Peierls transition temperature. ...

... The sky distribution of the BCGs from the HSS sample is shown in Fig. 6 together with BCGs from the SBS and Case surveys (Izotov et al. [ 1993b ]; Pustilnik et al. ... First, we compare the apparent magnitude distributions of the three samples. ... The similar behaviour of the faint end of the apparent magnitude distributions infers that the Northern BCG sample may have a similar completeness down to this limiting magnitude. ...

... At the simplest level of modelization, these phenomena are described by reaction-diffusion equations. The theory of this type of equation is far away from being fully understood but one can give however several results providing in some cases existence of solutions and their qualitative behaviour. ...

To achieve its task within the INTERBALL project, the subsatellite must have an orbit close to that of the main satellite and be at a certain distance away from the latter. ... For example, in case of the Tail Probe, to study the fine structure of boundaries between the formations in the interplanetary space (shock waves, magnetopause, magnetic clouds, plasma pistons, etc.) the distance between the subsatellite and the main spacecraft should be in the range of 100-300 km. ...
